Meiosis is a specialized cell division, essential in most reproducing organisms to halve the number of chromosomes, thereby enabling the restoration of ploidy levels during fertilization. A key step in meiosis is homologous recombination, which promotes homologous pairing and generates crossovers (C...

| 세포는 무엇인가? | 세포는 생물의 기본 단위이며, 그 유전 정보는 게놈 DNA에 기록되어 있다. 유성생식을 통해 세대진전을 하는 생물의 세포는 다음 세대에 유전 정보를 전달하는 역할을 하는 생식세포와 체세포로 대별 된다. | |
| 감수 제 1 분열기는 몇 단계로 나눌 수 있는 가? | 1 B). 감수 제 1 분열기는 염색체의 구조 변화에 따라, Lepton stage,Zigoten stage, Pakité Stage, Diploten stage, Deakinesis stage 등 다섯 단계로 나눌 수 있다(Fraune et al., 2012). | |
| 감수분열기의 세포가 RAD51 이외에 DMC1도 기능하는 것을 통해서 무엇을 예상할 수 있는 가? | 감수분열기의 세포는 RAD51 이외에 DMC1도 기능한다. 따라서 감수분열기 재조합은 RAD51과 DMC1의 양자가 협력하여 기능하는 것을 생각할 수 있다. 유전학적 해석으로부터 DMC1은 감수분열기 재조합에 필수이며, 중심적인 역할을 담당하고 있는 것으로 알려져 있지만, RAD51의 역할에 대해서는 아직 불분명 한 점이 많다. |
